A kind of digging and fixing device for planting pit in sandy land

Abstract

The invention discloses a pit-digging and fixing device for sand-land planting. The device comprises a power box, the inner center of the power box is vertically penetrated and provided with a centerrod, the bottom of the power box is vertically provided with a positioning cylinder, the outer wall of the positioning cylinder is encircled and provided with a fixing ring, the bottom of the fixing ring is fixedly connected with a positioning sheet, and the top of the fixing ring is provided with a connecting shaft around the positioning cylinder. According to the present invention, a transmission plate inside the positioning cylinder is driven to move towards a rotating head through the fixing ring, so that the inner magnet piece and the bottom of a rhombus plate are close to each other, sothat the bottom of the rhombus plate and the magnet piece are correspondingly fitted to each other, so that the top of the rhombus plate is inclined outwards and inserted into the inner part of the outer foundation pit side wall, and a pull rod is mutually clamped with the teeth of the side wall of the positioning cylinder under the action of a telescopic spring, which can effectively fix the foundation pit side wall. The device has the advantages of preventing the foundation pit from collapsing and reducing shaking without manual fixing.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a digging and fixing device for planting pits in sandy land. Background technique [0002] Our people's awareness of environmental protection is gradually deepening, and the country is also vigorously calling on the people to plant trees, but environmental protection also needs to be carried out according to the actual situation. In some areas in Northwest my country, due to serious land desertification, it is not suitable for planting taller trees. On the contrary, smaller thorny plants are easy to survive, so people usually plant this kind of plants on sandy land. [0003] However, the traditional planting method requires manual excavation of planting pits. This method is not only inefficient, but also because the sandy soil is relatively soft, it is easy to cause collapse when digging a large foundation pit, making it impossible to plant crops. The equipment i...
